PATENT OFFICE WISCONSIN, ASSIGNOR '10 KOHLER COMPANY, OF

KOHLIIB, WISCONSIN, A. CORPORATION OF WISCONSIN swmeme covnn, rozamsnwasnnns AND THE LIKE 1' Application filed November 18, 1925. SerialNo. 69,836.

vide such a cover which will produce acushioning effecton closing,preventin injury thereto even though it may be ma e of glass and alsopreventing 1n ury to the container though itmay have a vitreous enamelsurface.

Another object of the invention is to provide such a cover which willconstitute a glass drain board for a sink combined in the same fixturewith thedishwasher.

With the above and other objects in view the invention consists in asw1nging cover for dishwashers and the like as herein claimed and allequivalents.

Referring to the accompanying drawings in which like characters ofreference lndicate similar parts in different views,

Fig. 1 is a plan view of .a combined d shwasher and sink provided withthe swinging cover of this invention; 4

Fig. 2 is a sectional view thereof showlng the cover in elevation infull lines in its closed position and in dotted lines in its open pos1-tion' Fig. 3 is a front view of the cover in its open position;

Fig. 4 is an enlarged sectional v1ew through the cover at one of thehinges, and

Fig. 5 is a detail sectional View showing a modification.

In these drawings, 10 indicates the receptacle or container of adishwasher, which is preferably of enameled-iron ware and may be formedintegral with a sink 11, the cover for the container to constitute thedrain board for the sink.

The cover 12 for the dishwasher container or receptacle is preferably ofglass with or without a woven .wire re-enforcement embedded therein,though it may be of metal or of other suitable material and is pivotallymounted to lie either in an approximately horizontal closed position orin a vertical open position as by means of hinge members 13 bolted tothe .back of the dishwasher. The connections of the hinges with thecover and the dishwasher back are made with intervening gaskets 14 ofrubber or other cushioning material that will-prevent injury to theglass. cover or'the vitreous enamel surface. The hinges are preferablyofthe spring type to more or less counterbalance the weight of thecover.

Entirely surrounding the cover'is an inclined rubber flap 15 justbeneath the edge of the cover and spaced therefrom to engage theinclined surface of the rim of the dishwasher and form a yieldingsealing cushion between said rim and the cover. This yielding rubberflap 15 is preferably formed of a rubber'strip with a beveled or taperedinner edge confined between the bot tom surface of the cover and aninclined metal frame 16, where it is clamped by-nieans of screws 17threaded into headed metal posts 18 let through openings in the cover,as clearly shown in Fig.4. Where the hinges are located screws 19 aresubstituted{ for the screws 17 and they thread into he hinge members andcarry metal plates 20 with one edge turned over to engage the edge ofthe metal frame 16, the other edge engaging a rubber filler strip 21.The inner surfaces of both the hinge member and the clamp plate 20 areconcave so that the rubber engaged thereby will be compressed at theedges and will not, be spread and protruded by the clamping action ofscrews 19L The yielding rubber flap around the edge of the cover withits free edge spaced from the bottom of the cover forms a flexible lipthat will not only cushion the closing movements of the cover by itsresiliency, but b forming an air-tight sealing connection witli .the rimof the dishwasher so as to produce a dashpot effect causing the airwithin the receptacle of the dishwasher to become compressed and act asa cushion to stop the movement of the cover quietly and withoutinflicting a blow thereon that would be likely to break the glass.v Thiseffect is the same whether the springs are counterbalanced 01 not, forthe counterbalancing by the springs is not such as to overcome theweight of the cover in its horizontal position but merely to make iteasier to move thecover from one position to another and to reduce theblow struck should the cover be released and allowed to fall.

The air cushioning effect of the rubber flap is effective for producin asilent and harmless stop for the cover w en the cover is permitted tofall from any position.

In Fig. is illustrated a modification wherein the rubber flap is of thesame thickness and the metal frame '16 is paral- 15 lel with the cover.The cover 12' in this inof the cover.

stance is of metal and provided with a bead 21 on its bottom surface,against which the rubber flap bears to give it the inclination that willcause its edge to be spaced from the edge In addition to the sealingeffect of the flexible rubber li in cushioning the closing of the cover,it e ectively prevents thedischarge of water under the edge of the covereven 25 when the dishwasher is of the type'which depends upon forcefuljets of water thrown in all directions. As the rubber lip bears on anoutwardly inclined surface of the rim, there is no gutter or trap tohold water but the water is shed back to the bottom of the receptaclewithout being permitted to collect or escape. w

The cover when formed of glass ermits the operation of the dishwasherbeing observed and, whether of glass or of metal,

forms a drain-board for useful association with the sink. It may beslightly inclined to drain water to the sink. i

To protect the glass cover from injury by striking the back of thedishwasher the latter may be provided with a rubber bumper 22, as shownin Figs. 1 and 2.

While the invention is described as the cover for a'dishwasher, it will,of course, be understood to be applicable to clothes-washing machinesand various other apparatus of a similar nature and the term dishwasheras herein used is to be understood as including such other machines andapparatus.

What I claimas new and desire to secure by Letters Patent is':

1. A cover for the containers of dishwash ers or the like comprising ahinged cover member and a flexible sealing lip surrounding the cover andattached thereto and spaced from the edge of the cover to engage the rimof the container and form an air cushion therewith.
